The optical absorption has been studied under exposure to gamma radiation. Thin films of polypropylene were irradiated with a 60Co source and doses ranged up to 6 kGy. Analysis of the optical absorption spectra indicated that both direct and indirect electron transitions take place in the polymer. The observed optical energy gap (Eopt) and energy gap-tail (ΔE) for irradiated films were determined from the measured absorption spectra. The average values of (Eopt) and (ΔE) are 5.85 eV and 0.5 eV, respectively. There is no detectable change in the optical energy gaps and tails under the applied gamma-ray doses. |
